I used my Equinox a lot in longer grass, and also in very rocky areas.  The spoked design coils are never my preference but that's all the Equinox has.  I couldn't believe it when the Coiltek 10x5" came out as an open design and I asked if they intended to make a solid coil cover for it, they told me no they don't.  It would be very funny if Nugget Finder started making solid skid plates for the Coiltek Nox coils, In fact I hope they do. I noticed they have them for the Equinox 11" coil, so
